Applicationfiled February 5, 19321 Serial No. 591,102.

This invention relates to adevice which is particularly adapted to be secured beneath a refrigerator and to be connected with the door thereof in such a manner asto impart an opening and closing movement to the door for advertising purposes. 7

The main object of the invention is to pro vide a door oscillating device of the. character described which is adapted to be positioned beneath the refrigerator. in such a manner as to be out of view and to be connected with the refrigerator door so as to oscillate the same.

Another object of the invention is to provide a door oscillating device of the character' described which maybe quickly and readily secured beneath the refrigerator and which is well adapted for production at a lowcost.

Further and more limited objects of the invention will appear as the description proceeds and by reference to the accompanying drawings in which Fig. 1 is aviewpartly in section andpartly in elevation of a r-efrig-. era-tor having my door oscillating device con nected therewith; Fig. 2 is a-horizontal sectional view on the line 22 of Fig. 1 with the parts shown in the position in which they will appear with the door partially open;

Fig. 3 is a vertical sectional view on the line 33 of Fig. 1, and Fig.4 is afragmentary sectional view disclosing' the manner of connecting the door operating means to the door.

Referring now to the drawings, the reference character 1 designates a refrigerator having a door 2 and legs 3, 4', 5 and 6. 'Disposed beneath the refrigerator and between the legs thereof is a base member 7 which is, preferably rectangular in shape and pro-, vided with suitable legs 8. The base membearing member 12 which is secured thereto by bolts orrivets 13 ancll t.- Supportedby the bearing member -12 is a disk or plate .15 to which is secured a boss or projection 16 which is held in place by bolts or rivets 17 an'd18. The member 12, together with the. boss 16, providesa sort of thrust bearing adapted to receive a ball bearing 19 which rotatably supports the disk 15. The disk is provided about its periphery with an an'-' nular recess or depression 20 adapted tore; ceive a belt thereinthe purpose of which willhereinafter appear. I I

Carriedby the base member 7 is an electric motor M which drives a pulley 21 through suitable reduction-gearing provided within a casing 22. The pulley 21 drives the disk 15 through the medium of a belt 16; The belt 16 extends about the peripheryof the disk and fits within the peripheral recess 20. Also ley 23 which is carried by a bracket 24 pivotally secured to the base member by means ofza pin 25. Also carried by the base memidler pulley 23 serves to take'up the slack in the belt and to provide an operative driving connection between the. pulley 21 and the" disk 15. v

Disposed adjacent one side of the refriger ator is a supporting bar or bracket 29 which is of the same shape as the leg 5 and is secured thereto by means of clamps 30 and 31. Pivotally secured to the supporting member 29 is an angular link 32 which is held in place by brackets 34 and 35. Connected with one: end of thelink 32 is a U-shaped clamp on bracket 36 which engages the lower edge of the door 2 and which is provided with blocks 37 and 38 of rubber or other suitable material which serve to protect the surface of'the door- Pivotally, connected. with the disk 15 is a link 39 one endof which is pivotally connected to one end of the'link 32 by means of a .pin 10 carried, by the base member 7 is an idler pulthe motor with a suitable source of electric current.

The operation of the device is as follows: The motor M drives the pulley 21 through suitable reduction gearing enclosed within the casing 22. The disk or plate 15 is driven from the pulley 21 through the medium of the belt 16. The rotary motion of the disk 15 imparts an oscillatory movement to the refrigerator door 2 through the medium of the links 39 and 40 and the door is given an opening and closing movement so long as the motor is in operation. The entire mechanism is quickly and readily detached and moved from the refrigerator when desired. The apparatus is intended primarily for display purposes and is intended to be removed when the refrigerator is sold orotherwise disposed of. The apparatus consists of comparatively few parts which are cheap in construction and can be readily assembled or disassembled.

Various changes may be made in-the shape,

size and arrangement of parts without departing from the spirit of my invention and the embodiment of the invention herein disclosed is merely illustrative and the invention is limited only in accordance'withthescope of the appended claims.

Having thus described my invention, what I claim is:

1. A door oscillating member for use with a refrigerator comprising a base member and means for securing the same between the legs of a refrigerator, a disk rotatablymounte d on said base member, a motor operatively connected with said disk, a supporting member adapted to be secured to one leg of the refrigerator, an angular link pivotally secured to said supporting member and having one end adaptedfor connection with the refrigerator door and means operatively con-v necting the other end of said link with said disk whereby the rotary movement of said disk will impart an oscillatory movement to the refrigerator door.

2. A door oscillating device adapted for use with a refrigerator comprising a base member adapted to be positioned therebeneath, a rotatable member carried by said base member, a motor carried by said base memberand operatively connected to said rotatable member, a supporting member adapted to be secured adjacent said door, an angular link pivotally secured to said supporting member and having one end connected to said door, and operative connections between the other end of said link and said rotatablebase member, a motor carried by said base member and operatively connected to said rotatable member, a supporting member adapted to be secured adjacent said door, an angular link pivotally secured to said-supporting member and having one end connected to said door, operative connections between the other end of said link and said ro-' .base member adapted to be positioned'beneath the door, a rotatable member carried by said base member, a motor operatively connected with said rotatable member for rotating the same, a supporting member adapted to be secured adjacent the door, an angular link secured to said supporting member and having one end connected to said door and its opposite end connected to said rotatable member whereby the rotary movement of the rotatable member will impart a continuous oscillatory motion'to. the door.

5. A door oscillating device comprising a base member adapted to be positioned beneath the door, a rotatable member'carried by said base member, a motor operatively connected with said rotatable member for rotating the same,a supporting member adapted to be secured adjacent the door, an angular link secured to said supporting member and having one end connected to said door and its opposite end connected to said rotatable member whereby the rotary movement of the rotatable member will impart a continuous oscillatory motion to the door, the connection between said link and door including a U-shaped clamp adapted to engage the lower edge of the door.

6. A door oscillating device of the character described adapted for use with a refrigeratorcomprising a base member adapted to bespaced beneath the refrigerator, a rotatable member carried by said base member, a motor operatively connected to said rotatable member, a-supporting memberadapted to be detachably secured adjacent the door, an angularlink carried by said supporting 'member and having one end connected to said door and its opposite end connected to said rotatable member whereby upon operation of the rotatable member a continuous oscilla'-' tory motion will be imparted to the door, the entire unit being self-contained and adapted to be removed from beneath the refrigerator as a unit. y

In testimony whereof, I hereunto aflix my signature.
